I have a new Yorkie, 10 wks old, we're working through standard training such as house training, walking on a leash, etc...
One area I don't know how to handle is that he has begun to growl, bite and fight hard when trying to put on a harness, collar or sweater, which he needs early morning since the temperatures have been dropping around freezing. Since he's small, I can usually force the issue and get it on him, but then the next time I have to, he fights harder and growls more. I'm not sure how to handle this. Any suggestions?
